This invention relates to a hinge and is particularly adapted to hinges which must be subjected to very severe weathering and the like. 7

'An object of the invention is to provide an improved hinge which will operate easily and effectively in adverse environments.

Another object is to provide an improved hinge which willavoid clogging with dirt, snow, ice and similar materials.

Another object is to provide an improved hinge which will not require lubrication.

Another object is to provide an improved hinge which may be easily and economically manufactured.

Another object is to-provide an improved hinge in which wear will be reduced to a minimum.

Another object is to provide an improved hinge which may be quickly and easily assembled and disassembled.

Another object is to provide an improved hinge which may be produced without deforming any parts.

Other objects will hereinafter appear.

The invention willbe better understood from the description of two practical embodiments thereof, illustrated in. the accompanying drawings,in which;

Figure 1 is a side elevational view of one form of hinge embodying my invention;

Figure 2 is a top plan view of the hinge of Figure 1;

Figure 3 is a cross-sectional view taken on the line III-III of Figure l V Figure 4 is a partially elevational and partially sectional view of two of the parts shown in the preceding figures; and

Figure 5 is a view similar to Figure 4, but showing a modified form of construction.

The hinge shown is intended primarily for use on flaps of ventilators, one type of such ventilator being shown in the application of James B. Shaver, Serial Number 500,392, filed August 28, 1943, now Patent No. 2,492,242, dated December 2'7, 1949, although it will be understood that there-are many other situations where hinges of this type would be particularly advantageous.

Such ventilators are mounted on the roofs of buildings, frequently in positions which are relatively inaccessible, and are left to operate for long periods of time with a minimum of attention or servicing.

During the winter months of the year, they are 2 Claims. (01. -171) all times they are exposed to dust and dirt of various-kinds which seriously clog and abrade such devices, not to mentionthe effects of corrosion, particularly where exposed to fumes i which contain or mayform acids, and the like.

{For these reasons, the ordinary butt type of hinge is found unsatisfactory, requiring frequent lubrication, repair and replacement. r

The hinge illustrated consists of relatively loosely associated parts, which present large bearing surfaces with'consequent low unit pressures, and with ample clearance to permit the blowing away of large particlesof solid or liquid material. 9 a 7 7 As shown in Figures 1 to 3, onepart of the hinge consists of a flat base or plate l perforated at 2 to receive screws, bolts, rivets or the like, by which it may be secured to one of the elements which it is desired to pivot together, this plate having permanently fixed to it, as by welding 3, a piece of tubing 4 formed with alengthwise slot 5. V

Fixed to the other element which is to be pivoted is a fiat plate 6 of generally rectangular shape, also provided with perforations I for the reception of bolts, screws or rivets by which it may beheld to its associated parts, and having. adjacent its. exposed edge an elongated slot 8' slightly longer than the .piece of tubing above mentioned, and wide enough that the tubing may slide in this slot. 7

Another slotted piece of tubing 9 having an. external diameter slightly'less than the internal diameter of the first mentioned piece of tubing and of substantially the same length serves as a connector or pintle upon which the plate may rotate with regard to the first mentioned fitting.

It will be noted that the edge of the plate is recessed centrally so that it projects as two lugs Ill and H at its sides to locate this plate against Y axial movement relative to either or both tubes.

exposed to snow, sleet and rain which may freeze into ice in the parts of the mechanism-while at The smaller tube 9 has a lengthwise slot I2 and, at one end, a notch l3 diametrically opposite this slot.

The parts are assembled as shown by first placing the smaller diameter 9 tube within the larger 4, alining the slots of the two tubes, and then slipping the edge of the plate 6 into both slots and into the notch of the inner tube.

When the plate is now rotated about the common axis of the tubes, it will be apparent that the smaller tube 9 rotates with it, while the margin of the larger tube 4 projects through the slot 8 in the plate, preventing the disengagement of these parts in any position other than where the slots of both tubes are in allnement.

To maintain the plate 6 correctly on the diameter oi the smaller tube, the notch i3 is formed in one end of the latter diametrically opposite its slot, and arranged to be engaged by the projecting end of one of the lugs H! of the plate.

In use on a ventilator such as illustrated in the above mentionedpatent application, it will be apparent that with the plate I' clamped to the side of the ventilator and the plate 6 fastened, to the movable flap or damper thereof, the twou plates are never brought into right angle re1a-" tionship with each other, and; if, therefore, the, 15 1 slot 5 in the larger tube is that determined by af 1 diametrical plane through this tiibe perpendicuoflwhich is received into said notch, and the other bearing upon the end of the internally telescoped lar to its base plate I, the arts of the hinge can be assembled when one of the plates (Loiifil is, disconnected from its associated parts, and that, 3 b h, a es e eibeeer e ewed, 0, P13??- l. 0 la., he par h n e to, become separated until the bolts, rivets or erei re q nesi e aia r et. he two lat s mor n pe p m e ler, leii n "tube remote from said notch, and a hinged part fixedgtothe externalztu'be at a point remote from theslotl therein.
